THOMAS DE LA MARE, F TOOELE, UTAH.

CULVERT.

Application filed March 11, 1921. Serial No. 451,428.

To all whom it may concern:

Be it known that I, THOMAS DE LA MARE, a citizen of the United States, residing at Tooele, in the county of Tooele and State of Utah, have invented a new and useful Culvert, of which the following is a specification.

This invention aims to provide a culvert which may be fashioned out of metal, the

construction being such that the culvert may be manufactured cheaply, novel means being provided for connecting the various parts of the culvert.

Referring to the accompanying drawings: Figure 1 is a longitudinal section; Figure 2 is an end elevation; Figure 3 is a cross section; Figure 4 is a perspective showing one of the plates which make up the end member in the form shown in Figures'Q and 3.

The device as hereinbefore described preferably is made of sheet metal, corrugated or otherwise, and embodies an end wall made up of plates 28 overlapped at the top, as shown at 29, and provided adjacent their 25 lower edges with lugs 30. A securing element 31 unites the overlapped portions 29 of the plates, at securing element 32 uniting the lugs 30. The plates 30 have V-shaped notches 34 provided at their upper outer corners with reduced extensions 35. The plates 30 are provided with top flanges 36 and side flanges 37 having apertures 38 receiving securing devices 39 connecting wings 40 to the side flanges 37. The wings40 are supplied at their upper edges with outwardly projecting flanges 41'. The notches 34 define an opening 42 in the portal, adapted to receive the body portion of the culvert.

The body of the culvert includes a troughlike bottom 43 which is V-shaped in cross section, the side walls of the bottom being provided at their upper edges with outwardly extended flanges 44 having overhanging lips 45. The top of the body of the culvert is made up of arched crown plates 46, the transverse edges of which are overlapped as shown at 47 in Figure 1. The longitudinal edges of the crown plates 46 are bound between the flanges 44 and the lips 45 of the bottom. The member 43 fits in the opening 42 formed by the notches 44, one crown plate 46 coacting with the upper convened edge 50 of the opening 42, the flanges 43 and the lips being received in the extensions of the opening 42.

The bottom 43 of the trough is received in the opening 42, and the flanges 44, the lips 45 and the longitudinal edges of the top 46 are received in the extensions 35. The lips space the plates 28 from the top 46 at the edge of the opening 42 and because the plates are overlapped as at 29, and secured as at 31, these plates do not tend to sag down on the top 46 and the top may be inserted or removed without difficulty. The outstanding lugs 30 engage the bottom 43-at the longitudinal center thereof, and serve as a bracket which aids in supporting the bottom.

I claim In a device of the class described. an end wall comprising plates having notches provided at their upper outer corners with extensions, the notchescooperating to define.

an opening, and a body including a troughlike bottom comprising side walls provided at their upper edges with outstanding flanges having overhanging lips, the body including a top, the longitudinal edges of which are received between the flanges and the lips of the bottom, the bottom being received in the opening, and the flanges, the lips and the longitudinal edges of the top being received in the extensions, the plates being overlapped above the top to reinforce the end wall above the opening the plates being provided adjacent to their lower edges with outstanding lugs engaging the bottom adjacent to the longitudinal center thereof, a securing element-uniting the overlapped parts of the plates, and a securing element uniting the lugs.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

THOMAS DE LA MARE.
